Thin film artwork compounds |
| abstract |
A graphic artwork includes a thin film coating layer thereon which includes a cooper oxide which is substantially opaque to ultraviolet light and partially transmissive to visible light and suitable for printing circuiting on a printed circuit board or for other graphic artwork. In the case where the thin film compound includes unoxidized copper, etching thereof to achieve a predetermined pattern on the graphic artwork is facilitated by using a mixture of ammonium chloride and hydrogen peroxide. |
